I have always used a DVI cable to connect my computer to my monitor (with a DVI-I connection), but recently updated my MacBook Pro, and have realized that Apple has changed the connection they support. They only make Mini DisplayPort to DVI-D. The Apple genius at the store wasn't able to help me, or explain why they had made the switch. Right now I need to decide which connector to buy, and whether it makes sense to go out of my way to also get new DVI cables for my monitor setup.

I have a 23" Samsung monitor (1920x1080 resolution) with VGA and DVI inputs. The DVI input is currently being used by my other computer. Is this adapter capable of outputting a 1080p signal the the monitor through the VGA port?

I recently purchased a Mini-DVI to VGA Adapter to hook up my MacBook Pro to an external monitor, but the cord would not plug in to my MacBook because the laptop itself was too old of a version. The description says that this adapter is compatible with Mini Displayport and Thunderbolt ports. I'm fairly sure it will work for me, but I want to make sure before I spend another $30.00. Do Macbook Pros from mid-2009 have Mini Displayports?

My old MacBook I had a Apple Mini-DVI to Video Adapter, it was the most handy thing ever. I travel a lot and connect to many different TVs, Composite cable is the most common and easy to use. Especially when TVs are bridged together. But I can't find anything like that for the MacBook "Pro"? What can I do? I really need Composite video capabilities.

This is really bugging me. I want to hook my unibody mbp up to my tv via composite cable. Composite is roughly the analog components of VGA. VGA is analog, correct? but the pin-out on the mini display port does not specify a dedicated analog path. but it does have vague reverences to non-video data lines (pin 2 and 4)

I have tried mini DP ->DVI-I adapter, to a DVI-I -> component cable with no success. (implying no analog present at all)

so, how is analog getting out of the port for VGA? is there a feedback resistor inside the adapter which is communicating with the video card to specify digital for the DVI-d adapter, and analog for the VGA adapter? what this all is implying to me is you only get analog out of the graphics card with a VGA adapter and only digital with the DVI-d.

My LG Flatron L227WTG display won't accept it's full resolution of 1680x1050 when it comes from the mini DisplayPort (VGA). It WILL accept 1440 resolution, but not the 1680. I see no problems with the mini DVI port on my old MacBook.

Is this a problem with my display, cord, or did I just buy the wrong adapter? Would using a DVI input fix this? Or do I have to buy the upscaled HD Mini DisplayPort adapter instead?
